Javascript - Trying To Add A Client Side Event To A Dropdownlist And I Need To Access The Currently Selected Text?
Sep 1, 2010
I am trying to add a client side event to a dropdownlist and I need to access the currently selected Text. I have tried:
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text.Equals(' UNASSIGNED');");
and
ddl_tech.Attributes.Add("onclick", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.text.Equals(' UNASSIGNED');");
Both of which give me runtime errors when the event is fired.Whats the correct way to access this text property client side?I tried this but it does not enable the checkbox...
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').disabled = this.options[this.selectedIndex].text == ' UNASSIGNED';");
ANSWER:
Well, along with having to use == rather than .Equals, when you set a checkbox.enabled = false on the server side it raps the checkbox in tags and sets it to disabled=true; therefore you must set BOTH the checkbox.disabled = false and checkbox.parentElement.disabled = false; on the client side to enable the checkbox!The solution:
ddl_tech.Attributes.Add("onchange", "document.getElementById('" + chk_techreview.ClientID + "').parentElement.disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED'); document.getElementById('" + chk_techreview.ClientID + "').disabled = (this.options[this.selectedIndex].text == 'UNASSIGNED');");

I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.

Is there a way that I can execute a javascript function after the client side validation occurs in asp.net?I have a couple validation controls on a page and an input button with CausesValidation=true. The OnClientClick handler executes javascript before the validation runs, but i want to run some functions afterwards.

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript">
function NextClicked() {
var _ddlStatus = document.getElementById("<%=ddl.ClientID%>");
var _selectedIndex = _ddlStatus.selectedIndex;
var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) {
_btn.ValidationGroup = "G1";
}
if (_selectedIndex == 2) {
_btn.ValidationGroup = "G2";
}
}

I have a dropdownlist, and a Gridview where one of the columns is a dropdownlist. both dropdown lists use the same data source. When a value is selected in the dropdownlist (outside the gridview) I want to chaneg the selectedValue and selectText of every dropdownlist in my gridview. This is what I have tried:
Dropdownlist:
<asp:DropDownList onclick="javascript:onJDSelection()" ID="DropDownList3" runat="server"
DataSourceID="SqlDataSource4" DataTextField="circt_cstdn_nm"
DataValueField="circt_cstdn_user_id">
Javascript:
<script type="text/javascript">
function onJDSelection() {
var jd = document.getElementById('DropDownList3.ClientID').selectedText;
var grid = document.getElementById('GridView2.ClientID');
//Loop starts from 1 because the zeroth row is the header.
for (var i = 1; i < grid.rows.length; i++) {
var OtherText = grid.rows[i].cells[2].innerText; // Works fine
grid.rows[i].cells[3].getElementsById('ddl_JD').selectedText = jd;
}
}
When I click I get an error. It says object expected. However I know those objects exsist!

I have a scenario where i have 4 asp buttons , on click of each button there are 4 labels inside 4 seperate divs where each displays seperate data.
Now if i click second button i need to display second label text inside 2nd div and hide all other divs.How can i achieve this ?
OnClientClick event of each button calls displayAlternate() which displays repective div and hides other.
displayAlternate('second'); return false; --> if i do this server side event is not fired ...
If I return true div second label is not getting displayed..
How can I achieve functionality where all divs expect 2nd is hidden and i get server side event also..
Below is code.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head><body>
<form id="form1" runat="server">
<script type="text/javascript">
function displayAlternate(id) {

I have a content-sensitive firewall between my clients and my server. If we exclude SSL solution (it's not available in my case) then I was thinking of a javascript library which encrypts custom fields at client-side and a .NET class decrypts them at server-side. Is there any solution out of the box (maybe a server control) ?

ASP.NET newbie question - fastest fingers!
I have a page that needs to pull some script off the server, including tag info, for the page. Thus:
<html><body>
blahblahblah
<%: Model.TaggedField %>
</body></html>
Problem is, the value of Model.TaggedField may include HTML tags, but the page automatically converts the tag info to <myTag> etc.
What method can I call to make the value of Model.TaggedField be transmitted verbatim to the page?

I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.
I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:
Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...

I'm working on developing a custom control to select items from a predefined list. This is accomplished via 2 ASP.NET ListBox controls, with a few buttons to trigger the movement of ListItems from one ListBox to the other (lets call these ListBoxes lstSelected and lstDeselected).
This is easy enough to do in ASP.NET or JavaScript independently: I have both working. However, if modifications are made via JavaScript, ASP.NET retains no knowledge of this. Is there any way to register the creation of of options in a select tag without AJAX?
